Family Fun

Hello Bluffton,
I am new to the area and have looked and looked for things to do as a stay at home mom. I would like information!!! I have searched websites, newspapers, tourist information, etc.... Here are a few of the questions I have:
Where are the playgrounds in the area that are fenced in? (With more than one toddler at home, I need fences)
What restuarants are kid friendly? I mean highchairs - lots of highchairs!
I came from a town that had daily free things for children to do....are there any of those activities here?
Please Help...all ideas are welcome....my kids and I need some socailization! (ha)
